The best way to fight against greenhouse effects is to plant a forest. A forest breathes in carbon dioxide (CO2) and breathes out oxygen. Another way is to cool down the CO2 until it becomes a liquid and pump it down deep into the earth's layer under the sea. A 3rd way is to freeze the CO2 and sink it down into the ocean, where the freezing lumps will slowly dissolve. The latter two methods though, are very expensive and are still being tested. However, forestry is something anyone can do or support in some way.
